re: What is standard operating practice for additional costs incurred in home repair

Thanks for the advice.

I will compromise, there is no way I will pay their full amount.

ETA: I wish I could post their email with the invoice. It was a very aggressive and almost accusatory summary of some issues. This tone really came out of left field and made my blood boil. It makes me assume that this is a company that always has to fight with dissatisfied customers come collection time.
